The Lead Story - Preventing Lead Poisoning
Lead poisoning is a common type of poisoning but one that is preventable. While it can affect anyone at any age, growing children are particularly susceptible to lead poisoning.
Lead poisoning causes permanent damage to the developing brain and nervous system and can lead to brain damage, learning problems, and hyperactivity. Lead poisoning can also cause hearing loss, headaches, and growth retardation. Extremely high levels of lead can be fatal.
Lead has no value or function in the human body, and all exposure should be avoided. However, 6% of American children 1-2 years of age have toxic levels of lead in their bloodstream, according to the CDC (Centers for Disease Control and Prevention).
Lead is a naturally-occurring chemical in the earth's crust. The use of fossil fuels, mining, and manufacturing have spread lead throughout the environment into the water and soil. Lead-containing paint and pipes are still found in many older homes. Lead was widely used in paint until 1978. The renovation of houses built before 1978 can therefore release dangerous levels of lead dust, and improper removal of lead-containing paint can pose a significant risk of poisoning.
Lead is also found in old batteries, caulking, solder (a metal alloy used to join less fusible metals or wires), ammunition, and some pewter, pottery, and toys. In 2004, the US Consumer Product Safety Commission issued a recall of 150 million pieces of metal toy jewelry sold in vending machines that were found to contain lead after a child swallowed a piece of the jewelry and developed lead poisoning.
